After years of Zen Cart work, I'm still having trouble remembering where the settings are in admin, so I decided to document it and make it available all in one spot.  

First, the exact terms that are used in zen cart will be used here but I will also try to use search keywords that you might use when you don't know the exact terms.

The left hand menu is laid out exactly in the order of the Zen Cart admin and once I finish creating the pages, I'll also provide an interactive flash that you could download and use on your computer to access the pages. 

I do love Zen Cart but I do hate the admin.  It's not abnormal for an open source project to have a confusing admin and truthfully, that's one reason for me being able to make money as a Zen Cart expert.  But let's get real - it's time to lay it out!

At the moment, I've only gotten the configuration settings. Use the ask a question link if I haven't answered your question yet.

Note: 

This reflects information for 1.38a.  I am looking into 1.3.9a changes and will differentiate between the 2 once I find differences.

Important, but essential beginner information:

Your admin directory is located in the main directory where you installed your cart.  Mydomain.com is the cart so mydomain.com/admin is where your admin is located.  Mydomain.com/store - mydomain.com/store/admin.
